If there's history of colon/rectal cancer (lowercolon andrectumremoved) and 7 large polyps were found from an colonoscopy how often should a person go?

Need close observati: You need more close observation than general population, and colonoscopy in 6 months unlike usual surveillance colonoscopy. If all polyps are not removed even more frequently .If you your family members have colonic polyps, or colon ca family needs genetic counseling and tests.

Every year: Because of high risk of developing more colon cancer if continues to have more high grade polyps patient will require total colectomy and also the family members should be checked for polyposis.

Depends: Discuss with GI re: how thorough scope eval was. Ask if biopsied areas marked. Type of polyp (tubular, villous, sessile etc important predictors. May consider 6 month f/u scope, possibly 12 mo. Then annual until all negative then space every 2-3 yrs cautiously. Family history, genetic testing, upper scope should be considered.
